Abstract
This paper presents a process for obtaining glass ceramics based on corundum modified by borosilicate glass with various additives. The described Al2O3 /SiO2–B2O3–CaO–MgO–Na2O–K2O system has been developed for use in LTCC technology and exhibits a sintering temperature of less than 950°C. The impact of varying the sintering additive content on the firing temperature, microstructure, ceramic, and electrophysical properties of the resulting ceramics was investigated. The developed material exhibited a dielectric constant of εr= 6.73 – 6.82 and tangent of the dielectric loss angle of tan δ = 8.0 – 8.6 × 10 –3 at a frequency of f = 1 MHz.
